(Updated 8:53-a.m.) Severe thunderstorms that formed overnight in Nebraska, crossed into western Iowa early this (Monday) morning, bringing straight-line winds as high as 79 mph at some locations. Those winds caused large tree limbs to fall across Highway 59 near Denison, in Crawford County, and power lines to snap. A storm damage/incident report from the National Weather Service shows a 70-mile-per-hour just of wind caused a 12-inch diameter tree branch to crash through a window in Soldier, in Monona County. Winds averaging 65-70 mph were reported in Carroll and Crawford County, and a 79 mph gust was recorded southwest of Glidden.

As the storms continued eastward, they brought in excess of 65 mph winds to Jefferson, which caused numerous tree limbs to break and power outages. Significant damage was reported at the Spring Lake camping area near Jefferson. And, a large metal canopy over gas pumps at an abandoned gas station in Jefferson partially collapsed during the storm, and a grain bin partially collapsed near 130th Street and O Avenue, west of Paton, in Greene Couty.  Large tree limbs were also reported down west of Ames, as winds gusted up to 58 mph. Trees a big as 18-inches in diameter fell in Zearing.
